Abstract
In order to produce a filter cartridge for a reversible flow filter for filtering a fluid which comprises a filter cartridge interior surrounded by a filtering medium, whereby the filtering medium is adapted to be cleaned in a particularly effective and uniform manner during the back flushing phase, it is proposed that the filter cartridge should comprise a reverse flow damming body which is arranged in the interior of the filter cartridge and is movable in a longitudinal direction of the filter cartridge by the reverse flow when back flushing the filter cartridge and produces a local increase in the dynamic pressure of the reverse flow, whereby the reverse flow damming body does not abut against the filtering medium when back flushing the filter cartridge.
